In other words, the employment of students in the back is basically going to school.
Also, when taking the postgraduate entrance examination, the specialized courses are different. If I remember correctly, it is ideal to take 2-3 specialized courses, while the School of Information Science has taken about 5 courses, and they also have different settings in the research direction. These can be found in the recruitment announcement.
Generally speaking, the ideal in the difficulty of postgraduate entrance examination is relatively easy. But the easy part is that there are many people and competition is strong.
I hope I can help you and adopt it.
